Improvement in truss-pads



UNITED STATES NATHANIEL JONES, OF SYRAOUSE, NEW YORK.

IMPROVEMENT IN TRUSS-PADS.

Specification forming part of Letters Patent No. 136.735, dated March 11, 1873.

To all whom it may concern:

Be it known that I, NATHANIEL JONES, of Syracuse, in the county of Onondaga and State of New York, have invented an Improvement in Truss-Plates and Pads, of which the following is a specification:

Truss-plates have been made of metal shaped to suit the position where the same is to be applied, and elastic pads have also been made use of.

The object of my present invention is to produceatruss-plate or pad that is adapted to resting directly upon the surface vof the person without any injurious or unpleasant action, such as that resulting from thesulphur in hard rubber, and which is of a material that can be softened by a moderate degree of heat sufficiently to be bent yto the shape that 'is most convenient for and comfortable to the rupture to which it is to be applied, I employ pyroxyline or solid collodion prepared in either ofthe modes heretofore made use of 127,890, as representing the shape and character of truss-pad that can be made out of the composition aforesaid; and showing also the manner in which the parts are to be made for receiving the attaching-straps; but the shape of the pad or plate is to be such as to accommodate in the best manner the hernia to which it is to be applied. A truss-plate or pad made in this manner and of the aforesaid character can be warmed over a spirit-lamp, or otherwise, and pressed, molded, or bent to the shape best adapted to the hernia; the plate is much lighter than metal, and is free from the objection arising in the use of India rubber or its compounds from the sulphur contained therein. v

In the drawing, Figure 1 is asectional plan of a truss-plate with two projecting side pressers or pads, a b. Fig. 2 is a similar View with only one inward presser or pad c, and Fig. 3 is a section of a pad separately.

The parts are made of the aforesaid material, that is pressed to shape while suciently heated to be soft. The slotted recessed place d for the strap-hooks may be made of a metal plate set into the said material, or it may be made of the material itself. These figures illustrate a truss-plate and pad, but the shape of the same may be varied to suit the parts.

I claim as my invention- The truss-plate or pad made of `pyroxyline as a new article of manufacture.

Signed by me this 9th day of October, A. D.
